Abstract
Chemical sensors based on nanostructured semiconductor materials for the detection of refractory organics, such as nitrophenol, hydrazine and phenyl hydrazine, have been recognized as a very promising technology, which has attracted intensive attention from both academic and industrial fields in the past few years. In this short period, much progress has been made and the major aim to improve their performance has never changed. In order to shed light on its rapid development, a timely review is highly demanded. In this contribution, the recent progress in the synthesis of nanostructured semiconductor materials based electrochemical sensors for the detection of nitrophenol, hydrazine and phenyl hydrazine were summarized. The morphology of as-synthesized materials, the experimental conditions as well as their sensibility, detection limit and linear range are presented.
